The new species dealt with include the Braconid, Microbracon

 Ichneumonid, Gelis micvoplitidis, reared from cocoons of Microplitis 

 gortynae, Riley, parasitising Papaipema nitela, Guen. [nebris, Guen.), 

 and also a secondary parasite of P. niarginidens , Guen., from New 

 York ; the Eurytomid, Harnwlita lolii, occurring on Lolimn temulentnm 

 and L. midtiflontm in California, of which but one generation a year 

 is indicated, the adults emerging from the previous year's growth early 

 in the spring and ovipositing in the young grass of the current season, 

 the larvae maturing in early summer and remaining in the stems either 

 as larvae or pupae until the following spring ; the Pteromalid, Polyscelis 

 modestus, bred from Mayetiola destructor. Say, from Pennsylvania ; 

 the Eupelmid, Calosoter metallicus, reared from wheat stems containing 

 Harmolita sp., and from Mayetiola {Phytophaga) destructor. Say, from 

 California ; the Eulophid, Coccophagus saissetiae, reared from Saissetia 

 nigra, Nietn., from Panama Canal Zone ; and the Scelionid, Telenomus 

 {Prophanurus) busscolae reared from eggs of Biisseola fusca, Hmps.,
